[uClibc-cvs] uClibc/ldso/ldso/i386 elfinterp.c,1.27,1.28

[Erik Andersen]

Update of /var/cvs/uClibc/ldso/ldso/i386
In directory nail:/tmp/cvs-serv13904/ldso/i386

Modified Files:
	elfinterp.c 
Log Message:
Modify interfaces for _dl_parse_relocation_information()
_dl_parse_lazy_relocation_information() and _dl_parse_copy_information()
so they are all consistant, allowing for future consolidation.

Trim some trailing whitespace as well.
